| Abstract(in English) | In 2006, Iwamoto et al. introduced a visual secret sharing (VSS) schemes that allows rotation operation for shares in decryption. However, the proposed construction method is complicated and it only deals with 180-degree rotation. In this paper, based on the change of the expression of subpixels, the rotation angle for shares is extended into degrees besides 180-degree. Especially, a new VSS scheme, in which two shares can decrypt multiple secret images with appropriate rotation angles, is proposed in this paper. The proposed construction approach overcomes the shortcomings of the one proposed by Li et al.. It satisfies the information theoretical security and is simpler than preview works. Besides, it is also possible to extend the proposed schemes into n shares. |
